Objective:To investigate the clinical effect of locking plate combined with large autologous iliac bone implantation in treatment of complex proximal humeral fractures with comminuted proximal humerus and bone defect.Methods:A retrospective case-control study was conducted to analyze the clinical data of 52 elderly patients with proximal humeral fracture accompanied by comminuted and bone defect admitted to General Hospital of Jizhong Energy Xingtai Mining Group from January 2014 to March 2017. including 24 males and 28 females, aged 65-79 years, with an average age of 69 years. There were 36 patients with Neer's three-part fracture and 16 four-part fracture. Twenty-two patients were treated using locking plate combined with large autologous iliac bone graft (plate+ bone graft group), and 30 patients were treated using locking plate alone (plate group). The deltoid-pectoralis major approach was used in both groups. Operation time, bleeding volume and bone healing time were recorded. neck-trunk angle and shoulder joint range of motion were measured at the last follow-up . MOS 36-item short-form health survey (SF-36) score and visual analog scale (VAS) score were used to evaluate shoulder joint function and pain at last follow-up. Complications were observed as well.Results:All patients were followed up for 6-24 months, with an average of 17. 8 months. Operation time was (120.3±12.5)minutes in plate+ bone graft group, and (115.6±5.8)minutes in plate group ( P<0.01). Intraoperative bleeding volume was (400.8±15.8)ml in plate+ bone graft group and (300.2±16.2)ml in plate group ( P<0.05). Bone healing time was (2.2±0.5)months in plate+ bone graft group and (2.5±0.5)months in plate group ( P>0.05). At last follow-up, the neck-trunk angle was (132.3±10.6)°in plate+ bone graft group and (121.1±4.5)° in plate group ( P<0.01); the uplift and external rotation of shoulder joint was (149.2±3.7)° and (35.2±2.9)° in plate+ bone group, better than that in plate group [(135.1±2.1)°, (27.8±4.5)°] ( P<0.05). Meanwhile, the abduction and extension of shoulder joint was (118.4±13.9)°and (36.1±1.8)°in plate+ bone graft group, not significantly different from that in plate group [(110.8±21.9)°, (32.8±1.3)°] ( P>0.05). SF-36 score and VAS score in plate+ bone graft group was (87.3±4.7)points and (1.3±0.6)points, with significant difference from that in plate group [(70.9±7.2)points, (2.1±0.7)points]( P<0.05 or 0.01). One year after operation, 3 patients with humeral head varus and 1 patient with humeral head necrosis were observed in plate group, with the complication incidence of 13% (4/30); while 1 patient with absorption of humeral greater tuberosity in plate+ bone graft group, with complication incidence of (5%, 1/22) ( P<0.05). Conclusion:For complex proximal humeral fractures with comminuted proximal humerus and bone defect, locking plate combined with large autologous iliac bone implantation can maintain intraoperative reduction, avoid loss of neck-shaft angle, improve shoulder joint range of motion, promote function recovery, attenuate pain and reduce incidence of complications.

Objective:To investigate the factors affecting the effect of periprostatic nerve block (PNB), establish a prediction model of pain degree, and verify the prediction efficiency.Methods:The clinical data of 314 patients who underwent transperineal prostate biopsy in our hospital from June 2022 to January 2023 were retrospectively analyzed. The median age was 71 (65, 76) years, the median prostate-specific antigen (PSA) was 14.6 (10.70, 24.65) ng/ml, and the median puncture needle number was 21 (19, 23) needles, median prostate volume 45.86 (31.52, 67.96) ml, median body mass index (BMI)24.02(22.97, 25.33)kg/m 2, including 109 patients with a history of diabetes, 90 patients with a history of surgery, and 57 patients with a history of severe trauma. The patients were divided into mild pain group (1-3 points), moderate pain group (4-6 points) and severe pain group (7-10 points) according to the intraoperative visual analogue scale (VAS). According to the clinical characteristics, the factors affecting the effect of PNB were analyzed by univariate analysis and multiple ordered logistic regression method. R language was used to construct a nomogram model for predicting PNB effect, receiver operating characteristic (ROC) curve and calibration curve were drawn, and Hosmer-Lemeshow test was carried out to verify the prediction efficiency of the model. Results:The results of univariate analysis showed that 171 patients in the mild pain group had a median age of 71 (65, 75) years, a median PSA14.5 (9.6, 24.6) ng/ml, a median number of puncture needles of 20 (18, 22), and a median prostate volume of 34.94 (26.36, 45.12) ml, median BMI24.17(23.14, 25.79)kg/m 2, including 74 patients with a history of diabetes, 51 patients with a history of surgery, and 40 patients with a history of severe trauma; There were 110 patients in the moderate pain group, the median age was 71 (65, 76) years, the median PSA14.8 (11.03, 24.27) ng/ml, the median number of puncture needles was 23 (20, 24) needles, median prostatic volume 63.24 (49.14, 78.72) ml, median BMI23.91(22.58, 24.88)kg/m 2, including 26 patients with a history of diabetes, 29 patients with a history of surgery, and 10 patients with a history of severe trauma; In the severe pain group, 33 patients had a median age of 73 (67, 78) years, a median PSA14.6 (10.85, 34.80) ng/ml, and a median puncture needle number of 23 (22.5, 24) needles, median prostate volume 70.64 (61.50, 104.51) ml, median BMI24.32(23.00, 26.06)kg/m 2, including 9 patients with a history of diabetes, 10 patients with a history of surgery, and 7 patients with a history of severe trauma. The results of univariate analysis showed that the number of puncture needles ( P<0.01), prostate volume ( P<0.01), history of diabetes ( P=0.002) and history of major trauma ( P= 0.009) were the factors affecting the effect of PNB. Multiple logistic regression analysis showed that puncture needle number ( P=0.009), prostate volume ( P<0.01) and diabetes history ( P=0.041) were independent risk factors for PNB effect. The area under ROC curve (AUC) of the moderate and above pain prediction model was 0.872, P<0.01; the area under ROC curve of the severe pain prediction model was 0.817, P<0.01; the result of Hosmer-Lemeshow test of the moderate and above pain prediction model was χ2=5.001, P=0.757. The results of the severe pain prediction model were χ2=4.452 and P=0.814. The calibration curve was established, which showed that the prediction probability of pain degree was in good agreement with the actual risk. Conclusions:The number of puncture needles, prostate volume and history of diabetes are the risk factors affecting the effect of PNB. The prediction model of PNB effect based on this model can be used to predict the pain degree of patients undergoing prostate biopsy after PNB.

Objective:To investigate the effect of local anesthesia in patients with a PI-RADS score of 5 and ECOG score ≥2 for prostate puncture.Methods:Retrospective analysis of case data of 33 patients admitted to the Subei People's Hospital for prostate puncture from April 2020 to April 2022. Age (82.5±3.6) years. There were 18 cases with hypertensive disease, 8 cases with diabetes mellitus, and 6 cases with both diabetes mellitus and hypertensive disease. Body mass index (25.2±3.5) kg/m 2. prostate-specific antigen (PSA)(131.5±69.7) ng/ml. prostate volume (38.5±21.4) ml. all patients had a PI-RADS score of 5 on multiparametric magnetic resonance (mpMRI) and an Eastern Cooperative Oncology Group (ECOG) score ≥2. All 33 cases in this group underwent trans-perineal targeted prostate puncture using local anesthesia at the tip of the prostate. The visual analog score (VAS) and visual numeric score (VNS) were applied by the same surgeon to assess the patient's pain level and satisfaction at the time of puncture (VAS-1 and VNS-1) and 30 min after puncture (VAS-2 and VNS-2), and to record the duration of the procedure and the occurrence of postoperative complications. Results:In this group of 33 cases, the VAS-1 score was (1.9±0.3) and the VAS-2 score was (0.1±0.2); the VNS-1 score was (2.9±0.2) and the VNS-2 score was (3.9±0.1). Postoperative pathological results indicated that one of the 33 patients had a negative puncture result (pathology report indicating interstitial inflammation), while the rest of the patients had a positive puncture pathology report (puncture pathology report indicating prostate cancer), with a positive rate of 97%. One case of postoperative carnal haematuria occurred, which gradually improved after the patient was advised to drink water and take alpha-blockers. No perineal hematoma occurred, and all patients did not suffer complications such as urinary tract infection, urinary retention, azoospermia, vagal reaction, and infectious shock.Conclusion:In patients with a PI-RADS score of 5 and ECOG score ≥2, the use of single-hole local anesthesia for performing trans-perineal targeted puncture biopsy has the advantages of good paroxysmal pain and high safety.

Objective:
To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control.
Methods:
A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed.
Results:
A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95%
